RADIO RECEIVING CABINET.

' Application filed February 2, 1824, Serial No. 690,116. Renewed July 19, 1928.

where space is limited and often very costly.

The main object of my invention is to produce a radio cabinet provided with a receiving antenna orloop as part of the cabinet structure, so that normally the antenna occupies no otherwise needed space on or in the cabinet. The antenna-for the receiving set in my new cabinet is contained in a frame which is preferably in the form of a molding on the outside of the cabinet. This molding,

which may be as ornamental as desired, is

normally part of the outer cabinet structure, and is pivoted on the cabinet so that it may be swung into a position where the loopreceives the desired broadcasting. By virtue of this construction, the receiving antenna occupies no space in the cabinet and is normally nothing more than a molding on the outside of the cabinet. This molding may be on one of the upright walls of the cabinet, or it may run along the top edge of the cabinet,

depending upon the size, style and design ofcabinet employed. This feature of my inven- "ion is particularly applicable in cabinets of the so-called console and period types,-which in many respects are preferable to the upright cabinets, especially where a combined radio and phonograph cabinet is desired. The construction and mounting of the frame are such that when the loop is in vertical receiving osition, the verticalframe does not,

in any of its horizontally adjusted positions, pro]ect obstructively over the radio set in the cabinet. Consequently, the vertical loop never interferes with complete access to the radio set for tuningthe same or for any other purpose.

Viewed in another aspect, my invention comprises a radio cabinet in which a receiving loop is normally supported in horizontal position. The cabinet is of greater length than width, and the longer sides of the loop when in normal horizontal position run lengthwise of the cabinet. The loop is hinged to a side of the cabinet, so that it may be swung into vertical. receiving position with the longer sides of the loop vertical formaximum ef- ENT P t liciency. In a preferred form of'my invention, there is a plate 'orpanel pivoted to aside of the cabinet, and the'loop frame is mounted on the panel for raising into vertlcal position. When the loop is horizontal on the cabinet, the supporting plate or panel forms part'of the cabinet wall. The loopnormally takes up practically no space-I mean, no otherwiseuseful spaceand the result is a loop-equipped radio cabinet of compact construction. V The foregoing and other objects and advantages of my invention will become ape parent from a detaileddescription'of the accompanying drawings, which illustrate several cabinets constructed in accordance with my invention.

The cabinet, which I have indicated as a whole by K, is of the so-called console type, like a table orflat-top desk. There is a cen-- tral compartment, closed by a lid 1, for' phonographic reproducing mechanism, in,

cluding a sound amplifying horn or chamber 2. A compartment 3 maybe used for storing phonograph records. A third compartment 4 is used for housing a radio-receiving set, which may be or" any approved construction. In Fig. 2, there is a top panel or board 5, which carries the diflerent units of a radio set R. The panel 5 may be removably supported, as on a ledge 5. Below the panel 5, in compartment a, may be housed the necessary radio batteries. in Figs. 3 and l, the dotted outline B is intended to indicate diagrammatically a suitable term oi receiving set mounted in compartment 4. I

need not show or describe any par-tic lar form of radio set,'because my present invention has nothing to do with a radio set per se, and also because various kinds and types of radio sets may be purchased in the open market for installation in compartment A lid or cover 6 of suitable shape and dc forms the top for the radio compartment.

Along the outer top edge of the ca iinet runs a frame or molding indicated as a \ivhole by A. The construction and design of this moldingare preferably in accordance with the style and design of the'cabinet itself, so that the molding normally "forms, to the eye, an integral part of the outer cabinet structure. The frame or molding ll contains loops of wire 7 (see Fig. 4:) which are mounted in the molding in any suitable way. These wire loops constitute a so-called loop antenna, usually called a loop. The size and kind of wire to be used and the number of turns of Wire, are Well understood by radio experts. The precise construction of molding A is immaterial. It may be made of inner and outer strips of wood, with the loop wires, 7 laid between, or it may be formed out of moldable material suitable for cabinet work, or in any other practical way, depending upon the design and material of he cabinet and upon the skill of the cabinet maker.

Molding A which is constructed separately from the-cabinet, normally rests in a horizontal position along the top edge oi'f'the cabinet, as shown in Fi 1. However, in order that the loop carried by the molding may be placed in an upright position for receiving radio impulses, the molding A is so mounted on the cabinet: that it may be raised into vertical position thereon. For this purpose, the molding is hinged at one end to the cabinet. This connection is made in any practical Way, but at the present time I prefer connecting the molding to the cover 6 of the radio set. This ma. 1 be done by simply gluing or otherwise fastening the moi-dim sides and outer end of cover 6, w hinged to the top of panel 8 arr-an end of the cabinet. A long hing; 101' t; cover 6 is shown at 9 in Fig, 4;. By sim lifting the cover 6, the loop frame 01' mo ing A is automatically raised into vertical receivingposition. lhe cover 6 forms not v molding may only a lifting means for the loop frame, but it also acts as a stitiening means for the frame, which is naturally of light construction.

Suitable means may be provided for bracing the cover 6 and molding A in raised position. In the dra mgs, 1 have shown a bracing hinge normally mounted in a recess 10 of panel 8. This hinge comp-rises a member 11 rigidly secured to the panel 8 and a pivoted arm 12 having a slot 13 at its free end for engaging with a turn-button 14- on a' direction after it has been raiset into upright position. In the present instance, 1 provide for this horizontal adjustment of the loop y hinging the panel 8 at one end to the body of the cabinet, as by means of hinge 16. This hinge may be of the form known piano hinges, thereby insuring suhicient strength.

The leading out wires of the loop may be arranged in any convenient way. In Fig. 3, the point. and 18 indicate where the two ends of the loop are brought out through the cover The wires 19 may either be continuations of the loop r "es, or they may be separately connected to the loop at the points 1? and 18. The connecting wires 19 are preferably led toward and past the hinge 16, and from there through the cabinet into the radio compartment where they are properly con nected to the radio set, as will be understood. In this way, there is but little slack required in the wires 19 to allow for the hinge mcvemerits of cover 6 and panel 8.

it will be seen from the fore oing that l have provided a simple and eas adjustable mounting for a loop on radio cabinet as part of the abinet structure itself. When theparts are in normal position, as shown in Fig. 1, the loop forms an integral invisible part oi? the cabinet structure. l l hen it is desired to operate the radio set, it is only ecessary to throw open the lid 6, thereby automatically raising the loop into vertical position and at the same time exposing the panel 5 of the radio set for tuning. Tue cover 6 and loop molding A are braced in 12 to the turn-button be swung horizontally out the hinge 16 of panel 8, until it occupis the correct receiving position, as will be clear to those skilled in the radio art. The panel 8 has a sfiing ot approximately 180 deloo grees, as indicated Fig. 5, where the normal position of the panel 8 is shown in full lines and the extreme open position in dotted lines 8. This movement is sufficient to take in all the directions of the compass.

To place the parts back into normal position, it is only necessaryto disconnect the brace arm 12, which may be folded down into the recess 10. of panel 8. Thereupon, the panel is swung back into normal position. on the cabinet, and then'the lid 6 and molding A are lowered onv the cabinet into the posi:

tion shown in Fig. 1. If desired,small strips or beading 20.1nay be fixed along-the top edge of the cabmetto form a rest for the molding A when in normal position, as shown in Fig. 4. It will be understood that the molding A in normal position does not interfere with the opening and closing of the receiving radio impulses. I

It is also possible to utilize the receiving antenna or loop in frame A in horizontal positionwithout adjusting the frame. For the reception of vertical waves, the horizontal antenna would not be in the form of a coil or loop, but the wires would be arranged and connected to act as a regular outdoor antenna consisting of one or more horizontal wires. Such an antenna in molding A would require a ground connection and be otherwise properly connected with the radio-receiving set, as those familiar with radio will understand. However, for the reception of hori zontal wavesthat is, electric oscillations propagated in a horizontal plane,the loop 7 in frame A is used in a horizontal position without grounding, the same as in vertical position. forming a double function: in vertical position it picks up radiant energy transmitted by vertical waves, and in a horizontal position it receives radio-broadcasting on horizontal waves. The adjustment of the loop from vertical to horizontal, orvic'e versa, is quickly.

Of course, when and easily accomplished. the loop 7 is used in a horizontal position, the radio set R is mounted in the cabinet so as to be readily accessible. For instance,it could be mounted in the compartment closed by lid 1 which. as previously stated, can beopened and closed while the loop frame remains in horizontal position on the cabinet.

It is immaterial at which end or side the molding A is-hinged on the cabinet, although The loop 7 is thus capable of per v it is preferable to hinge it at one end, so as to utilize the length of the cabinet for the vertical height of. the loop. The frame or molding carrying the loop will vary in outline, shape,

design and construction to conform to the particular size and style. of cabinet for which it is intended. Since the loop-carrying molding may be formed of strips of wood, or other material easily bent into various shapes, my inventionis readily adapted to any kind of cabinet suitable for radio mechanism and, if desired, also phonograph mechanism;

It will be seen from the foregoing description that my invention provides 1 for the mounting of a loop on a radio cabinet in such away that the loop-carrying frame is normally part of the cabinetstructure itself, so Y that the loopis to all intents and purposes invisible and occupies no extra space. At the same time, the loop iseasily ad usted on the cabinet into correct receiving positionf 'When the radio set. is not in use, the loop frame for molding is readily swung back into normal position on the cabinet.

T hus, my new and novel loop mounting makes pos sible a self-contained radio-receiving cabinet, or a combined radio and phonograph cabinet, in which all necessary parts for ra dio reception are embodied in the cabinet structure itself. Such a compact seltcontained radio cabinet, which requiresno outside aerial orseparately mounted. indoor loop, is especially desirable in apartments where space must be utilized to the best advantage.

My invention is readily adapted to radio. cabinets of dlfierent design and construction;

Other arrangements and modifications involving the main idea of my invention will occur'to those skilled in the art.
